IMPORTANT
Check that when the coolant pump is active, the coolant circulates in reverse order to
the usual circulation.
Check the cleanliness, condition and fitting of the coolant pump.
Top up the coolant if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any harness damage, and check the condition and connection points of the injection computer and the
coolant pump connectors.
Repair if necessary.
If the fault is still present, check for +12V on track 2 of the coolant pump.
If the +12V is not present on track 2 of the coolant pump, check the following connection for insulation,
continuity and the absence of interference resistance:
Coolant pump track 2 track 1, connector PPM1, of the Protection and Switching Unit
Repair if necessary.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connections:
Computer, connector C, track L4 track 1 of the coolant pump
Repair if necessary.
If the fault is still present, check that the resistance between tracks 1 and 2 of the coolant pump is neither zero
nor infinite.
Replace the coolant pump if necessary.
If the fault is still present, deal with the other faults then proceed to the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
